Utilizing an Individually Built Mobile Robot in the Laboratory of an Advanced Digital Logic Design Course in Conjunction with a Final Class Competition

This paper describes the development and implementation of a series of laboratory projects utilized in a junior level, required course for computer engineering majors titled, “Advanced Digital Logic Design.” Eleven of the 13 lab experiences are directly related to this project. The first five labs are mainly construction labs where students are developing practical hands-on skills and gaining familiarity with common prototyping practices. These skills include (a) utilizing a 3-D printer in order to create the chassis, wheels, and sensor mounts, (b) disassembly, modification, and reassembly of two servo motors, and (c) assembly and soldering two custom-designed printed circuit boards (PCB) totaling approximately 50 components and 200 solder points. Once the all the subsystems are complete, then they are screwed together, along with a battery pack and front contact sensing bumper. In the final six labs, the students systematically build-up the various digital designs needed in order to autonomously control their individually built mobile robot. These labs include digital designs (a) to control the servos, (b) to play an accurate song on a small speaker, (c) to communicate with five infrared (IR) distance sensors in order to obtain range information, (d) to create a complex finite state machine (FSM), and (e) to control the overall behavior of the robot. A 240 logic cell Complex Programmable Logic Device (CPLD) limits each student’s design space and, consequently, efficiency of implementations is enforced. Milestones are graded throughout the semester in order to encourage proper progress toward the goal of participating in the final class competition; this event is where guests are invited and small prizes are awarded for the top three finishers. This style of project-based-learning provides students with opportunities to gain practical skills and, with these skills, to increase confidence in their abilities to design and solve real-world problems. Additionally, I have found student motivation and interest to be high, which leads to increased rates of learning and accomplishment. Since the cost of the components is kept low (approximately $60), each student retains his/her respective robot and can continue working with it beyond the completion of the course

Establishing uranium migration parameters for the Indian Springs Range

For the past 24 years, depleted uranium (DU) kinetic energy penetrators used by the US Air Force have been tested and evaluated to develop targeting system algorithms at a site in the Mojave Desert. This two-fold study focused on reducing uncertainties in the environmental parameters used to model DU migration in arid soils through extensive soil characterization; and evaluated potential horizontal migration of DU through close examination of erosion tracts traversing the target area. Model error reduction was achieved by developing site-specific parameters for DU migration on various impacted soil horizons. Parameters determined in this work included distribution coefficients, soil texture, soil pH, uranium activity concentration, and soil particle density, as well as characterization of motile playa layers subject to sporadic flash flooding events. Using these values in the Residual Radiation (RESRAD) computer code resulted in an individual\u27s first year total dose of 35 mrem under a resident farmer scenario. A sensitivity analysis was performed on several parameters, identifying the soil distribution coefficient (Kd) and density as the most significant to source removal and dose reduction. Data generated from RESRAD provided 238U soil clean up criterion of 200 pCi g-1 for decommissioning based on agricultural land usage requirements, and a limit on the sum of exposures from all model pathways to 25 mrem per year. Observations were made validating DU transport by erosion with activity concentration decreasing exponentially with distance. Recommendations are made to help mitigate the DU surface transport processes

Assessment of behavior and personality characteristics of master\u27s level counselor education students across training and supervision

Calls for a more prescriptive, individually tailored approach to counselor training have recently appeared in the literature. The focus of this study was the assessment of behavior and personality characteristics of master\u27s level counseling students and to determine if change occurred among these characteristics as a result of counselor training and supervision or to the gender of the student.;Behavior was assessed using the Hutchins Behavior Inventory which measures the thinking, feeling and acting domains of behavior. Personality characteristics were measured using the Adjective Checklist and the California Personality Inventory. Data from eighty-five students were used.;Discriminant analysis was used to determine if personality characteristics discriminated the behavior groups. Additionally, repeated measures multivariate analysis of variance and the univariate analysis of variance component of the discriminant analyses were used to determine if change occurred.;Students differed across the behavior groups. Further, selected personality variables discriminated the behavior groups. When the discriminant function was used 85.88% of the students were classified correctly. Additionally, change was observed across training and supervision. The gender of the student was not significant in this analysis. The interventions of counselor training and supervision appeared to cause the change

A Critical Spatial Econometric Counter Analysis of the Impact of New Toxic Facilities on Local Wages

Hegemonic assumptions and industry claims regarding the benefits of new toxic industrial facilities on local wages are tested and challenged. Analysis is performed by applying GIScience and Spatial Econometric methods within a critical framework. A call is made to develop more broadly the practice of Counter Analysis, which is presented as an analogue of Counter-Mapping that repurposes Spatial Analytic methods for the pursuit of critical research agendas
